Gracias por tu respuesta. Mira te copio y pego el código de mi archive.php
Código PHP:
<?php
get_header(); ?>
<section id="primary" class="content-area">

<?php if ( have_posts() ) : ?>
<header class="page-header">
<h1 class="page-title">
<?php
if ( is_category() ) :
single_cat_title();
elseif ( is_tag() ) :
single_tag_title();
elseif ( is_author() ) :
the_post();
printf( __( 'Author: %s', 'modernwpthemes' ), '<span class="vcard"><a class="url fn n" href="' . esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ) . '" title="' . esc_attr( get_the_author() ) . '" rel="me">' . get_the_author() . '</a></span>' );
rewind_posts();
